摘要
用金属氧化物改性滤料强化过滤除酚的试验表明,改性滤料对苯酚单纯的吸附过滤去除效率不高,而滤前预投高锰酸钾对苯酚的去除非常有效。改性滤料表面的吸附和催化作用是除酚的主要机理。
Experiment was made on the enhanced filtration for phenol removal by using modified metal-oxides-coated filter media.The result showed that for the modified filter media,the adsorption filtration alone has less removal rate of phenol,and it is very efficient to dose potassium permanganate before filtration.The adsorption and catalysis of the surface of modified filter media are the primary mechanisms of phenol removal.
